推荐答案

您可以像在DataList中添加其他控件一样添加图像控件.你有什么问题?

要刷新UpdatePanel，您需要以某种方式触发它.在UpdatePanel内或外部添加一个隐藏按钮(并为UpdatePanel设置触发器).使用JavaScript(如setInterval)自动单击按钮.

You add the image control just like any other control in your DataList. What is the problem you are having?

To refresh the UpdatePanel you need to trigger it in some way. Add a hidden button, either within the UpdatePanel or outside (and set the Triggers for the UpdatePanel). Use JavaScript, like setInterval, to automatically click the button.

window.setInterval(refresh, 500);
function refresh()
{

(" ). (); }

("#refresh button id").click(); }
